If your old TV is looking tired, now's a good time to make the move to 4K. Samsung's UN43NU7100 offers impressive picture quality and smart TV conveniences for a sub-$500 TV. Its super-crisp 4K picture has four times the detail of HDTVs.

Ready to upgrade from HD?

If your old TV is looking tired, now's a good time to make the move to 4K. Samsung's UN43NU7100 offers impressive picture quality and smart TV conveniences for a sub-$500 TV. Its super-crisp 4K picture has four times the detail of HDTVs.

Although this model is compatible with HDR (High Dynamic Range) content, it doesn't have the extended color range to make HDR colors pop. And its LED backlight lacks local dimming, so it can't reproduce the picture contrast extremes of HDR material. Still, this basic model looks fine with standard (non-HDR) TV content.

A better looking picture with everything you watch

When you unbox the UN43NU7100 you'll want to start watching right away. The TV's built-in set of streaming apps makes it easy. If you're an Amazon Prime subscriber, you can start watching gorgeous 4K shows and movies right away — for free! Another great source for streamed 4K content is Netflix®.

But you definitely don't need native 4K content to enjoy the UN43NU7100's picture. Samsung's UHD Engine automatically upconverts any signal to match the screen's 4K resolution. All your current video sources will look better than ever.

Speedy web apps and streaming, no waiting

The UN43NU7100's speedy Quad-Core processor lets you browse the web without having to interrupt what you're watching. Whether your connection is wired or wireless, you can switch between apps, stream content, and multi-task much faster than with previous smart TVs.

Video Section

4K UHD Engine w/ Upscaling: The Samsung UHD TV has
a display resolution of 3,840 x 2,160 (4K) and will display all video at
that resolution, regardless of input signal, thanks to UHD upscaling. 4K
delivers 4x higher resolution than current 1080p high-definition TVs, so you'll
see more on TV than ever before with over 8 million individual pixels (3,840 x
2,160) compared to about 2 million (1,920 x 1,080) on your 1080p HDTV. UHD
Upscaling delivers the complete Ultra-HD picture experience with a
proprietary process including signal analysis, noise reduction, UHD
upscaling, and detail enhancement to seamlessly upconvert SD, HD, or full-HD
content to Ultra-HD-level picture quality.

Note: This TV complies with the CTA 4K Ultra High-Definition Connected
definition requirements. The trade organization known as the Consumer Technology
Association (CTA) is considered an industry authority on engineering standards
for consumer electronics in the United States. Visit
www.cta.tech for more
information.

HDR (High Dynamic Range Video): The Samsung UHD TV features
the ability to provide a premium High Dynamic Range (HDR) experience, with a
higher level of contrast between light and dark images. HDR delivers a much
higher level of contrast between light and dark to produce an image that is more
realistic and closer to what the content creator imagined. This increased
contrast reveals the subtle nuances of the image, from detailed blacks and
shadows to the brightest whites and colors, plus greater depth. In addition to
supporting the standard HDR10 format, the Samsung UHD TV also supports HDR10+
and HLG; as well as HDR+.

HDR+: One of the biggest benefits of HDR+ is its
ability to upgrade Standard Dynamic Range (SDR) content to HDR-like picture
quality, allowing viewers to enjoy all of their favorite content in the
highest picture quality possible. With HDR native content, HDR+ also
uncovers previously hidden images from darker content scenes, supplementing
the level of brightness to express objects hidden in darker shadows. For
brighter content scenes, HDR+ increases the level of contrast ratio to
differentiate objects from the background, while still depicting more image
details on the screen for an overall better picture.

HDR10+: Samsung Electronics and Amazon Prime Video
announced the entire Prime Video HDR library is now available in
HDR10+, a new open
standard that leverages dynamic metadata to produce enhanced contrast and
colors on an expanded range of televisions. Prime Video is the first
streaming service provider to deliver HDR10+ content to its users. The
HDR10+ technology on Prime Video incorporates dynamic metadata that allows
the Samsung UHD TV to adjust brightness levels on a scene-by-scene or even
frame-by-frame basis. By applying individualized tone mapping to each scene,
HDR10+ delivers an incredible viewing experience. The picture quality offers
an enhanced visual experience with more detailed expressions, brighter
shadow areas and more accurate color renderings that stay true to the
creator's original intent.

HLG: HLG (Hybrid-Log Gamma) is primarily designed for
live video feed and over-the-air broadcasts. It uses no pre-encoded metadata
and is backwards compatible with SDR. HLG's native compatibility allows much
of today's existing SDR infrastructure to be re-used for HDR in the future.

PurColor: PurColor allows the TV to express most shades of color
as nature intended for optimal picture performance. Most TV's focus on the
adjustment points of primary colors Red, Green and Blue. PurColor focuses on
primary and secondary colors Magenta, Cyan and Yellow.

Contrast Enhancer: Flat images come to life with Samsung's
Contrast Enhancer. The UHD TV intelligently applies
varying levels of contrast enhancement to different areas and objects on the
screen creating a dramatic 3D-like effect. As a result the TV can provide a
realistic viewing experience with depth.

HDMI 2.0a Inputs: The Samsung UHD TV is equipped with three HDMI 2.0a inputs to connect to your Blu-ray
player, Satellite/Cable receiver, Game Console, and/or AV receiver. Any HDMI
input can also be used to connect a PC to this TV. All HDMI inputs are 4K
compatible, HDCP 2.2 compliant, and support 4:4:4 color subsampling. Please use a premium high speed HDMI cable with 18 Gbps and above to
view 4K HDR content.

Color Subsampling: With 4:4:4 color subsampling, luminance
(brightness) and chroma (color) are sampled at the same rate; resulting in
an RGB color palette as big as the video sampling rate for a video image
with more total colors, plus greater color accuracy and detail. 4:2:2
(50/60p) and 4:2:0 (50/60p) are also supported by all HDMI inputs.

Notes: This TV does not contain analog composite or component
video inputs.

Analog Video Inputs: The Samsung UHD TV also features a
single component video input which will accept 1080p (24/60Hz), 1080i, 720p,
480p and 480i video signals. The component video input can also be used as a
composite video input (480i only). Use the included AV adapters to make an
analog audio/video connection.

Picture Controls: You can make the following adjustments for
an optimum picture. The TV's picture adjustments can be made for a particular AV
input or for all inputs.

Picture Modes: Picture Modes apply preset adjustments
to the picture. Select from Dynamic (increases the brightness of the
screen), Standard (suitable for a normal environment), Natural (useful for
reducing eye strain), or Movie (darkens the screen and reduces glare).

Manual Picture Settings: The TV has several options for
manually adjusting the picture quality. Manually adjust Backlight (adjusts
the brightness of the LED backlight), Contrast (increases or decreases the
contrast between dark and light areas of the picture), Brightness (adjusts
the brightness level of the picture) Sharpness (sharpens or dulls the edges
of objects), Color (adjusts the color saturation of the picture), and Tint
(adjusts the amount of green and red in a picture).

Film & Games Modes: The TV can be set to automatically
sense and process film signals and adjust the picture from optimum quality. When the
Game Mode is activated, the TV's settings are automatically optimized for an
enhanced gaming experience with minimal input lag and ultra fast refresh
rates (not available for normal TV viewing).

Built-in HDTV Tuner: The TV features a built-in over-the-air HDTV (ATSC) and Clear QAM tuner, so you don't need a separate
set-top box to receive and decode over-the-air HDTV/SDTV or unencrypted Digital
Cable signals (up to 1080i); subscription still required to receive cable
channels. A single RF-type coaxial input is use to connect an
external indoor/outdoor antenna (sold separately).

Audio Section

ARC (Audio Return Channel): The Audio Return Channel within
the television's HDMI 3 input enables the TV, via a single HDMI cable, to send
audio data "upstream" to an A/V receiver; increasing user flexibility and
eliminating the need for any separate S/PDIF audio connection. This feature
allows audio to be sent from the television to your A/V receiver through the
same HDMI cable already being used to send audio/video to the television. This
eliminates the need for extra cables connected to the TV. ARC allows audio from
the TV tuner, Network connection, inserted USB device, or HDMI inputs to be
heard through your ARC compatible AV receiver via the television's HDMI ARC
input.

Note: Both the television and the receiver must support
ARC for this function to work properly. When connecting an A/V receiver that
is compatible with Audio Return Channel (ARC), connect it to the TV's HDMI 3
input. If connecting a system that is incompatible Audio Return Channel
(ARC), an additional audio connection via Digital Audio Out (Optical) is
necessary. The TV's speakers are muted when using ARC function.

Audio Delay: The Audio Delay function corrects audio/video
mismatch, when watching TV or video, and listening to a digital audio output
using an external device such as an AV receiver. You can adjust the audio delay
from 0ms to 250 ms.

Network/Internet/USB Functions

Samsung's Quad-Core Processor: Samsung's Quad-Core
processing speeds allow you to perform multiple tasks at the same time, such as
using an app while downloading another one. It also enables extremely faster web
browsing and application access. Quad-Core eliminates lag to give you a fluid

(such as photos & videos) to the Samsung UHD TV without connecting to your
home network. WiFi Direct completely bypasses your WiFi access point/router,
so it's easy to set up. Streaming of copy-protected content and other
certain formats are not supported.

Note: A dual-band Gigabit wireless-N router or better is
